Hi,

During a test rebuild of HDF5's reverse dependcies against HDF5 2.1.0
currently in experimental, haskell-hdf5 FTBFS with:

src/Bindings/HDF5/Datatype.hs:183:13: error: [GHC-88464]
    Variable not in scope:
      h5t_decode :: InArray CChar -> IO Bindings.HDF5.Raw.H5I.HId_t
    Suggested fix:
      Perhaps use one of these:
        ‘h5p_decode’ (imported from Bindings.HDF5.Raw.H5P),
        ‘h5t_decode1’ (imported from Bindings.HDF5.Raw.H5T),
        ‘h5t_encode’ (imported from Bindings.HDF5.Raw.H5T)
    |
183 |             h5t_decode (InArray buf)
    |             ^^^^^^^^^^


H5Tdecode() was deprecated starting with HDF5 2.0.0. I'm not familiar
at all with Haskell so I don't have any clue how to patch haskell-hdf5
so that it builds correctly against HDF5 1.14.6 in unstable and HDF5
2.1.0 in experimental.

Thanks in advance,
_g.
